Does day-of mode work without signal?
No. It is a live page, and being live is the point: it refreshes when anyone edits, every minute, and each time you return to it. If the venue has poor signal, print the seating packet as a backup and keep day-of mode for the changes.
See How do I print my seating chart? for the packet, which lists every table with its guests, meals and dietary needs.
